"Canon” and “not canon” in the Adventure/02 universe
This is something I want to talk about, because it has a certain degree of relevance to the question of what I choose to take into account in my analyses and what I don’t. I write a lot about Adventure and 02 because both series are ridiculously consistent over their 104-episode runtime, but there are times when things contradict or don’t quite track together, and I have to figure out how to best rationalize them -- which means I need to make arbitrary decisions on what to count and not count, and when one does make those kinds of decisions, you’re very liable to get the complaint: “but that’s not canon!”
Which always makes me think: who decided that? And in the end, this is something that I think extends beyond just Digimon; every fanbase for everything always wants to believe there’s a clear-cut answer to things that everyone’s supposed to follow in a canonical timeline, and things that fall outside it. And sometimes, for some franchises, that is doable, because official staff will actually say outright that “this counts, and this doesn’t.” But that’s not how Toei and Bandai work, and their modus operandi has always been to toss a bunch of often-contradictory stuff at everyone and go “figure it out yourself,” and I think at some point the fanbase really needs to acknowledge that this so-called clear-cut boundary of “canon” and “not canon” doesn’t actually exist at all. Or in other words, any assertion of something being “canon” or “not canon” in the Adventure and 02 universe is purely something arbitrarily defined by fans, and was never determined by official - which, conversely, has actually encouraged you to take as much as you want and figure out the rest yourself.
Before we begin, I do want to make clear that this is not about one’s personal canon based on one’s own preferences -- that is to say, if you’re going “I don’t consider this canon because I don’t like this/don’t want to work with this,” then that’s entirely your right, especially if you’re doing creative work and need to decide what to apply and to not to apply. (Although, as always, one must be conscientious and respectful of those who do like it and consider it canon, because everyone’s going to differ on this.) What I am talking about is when people take a substantial part of the franchise that they otherwise like, such as a movie or drama CD, see one detail that’s contradictory in terms of the timeline or lore, and take that as evidence of “yep, the entire thing’s not canon. We’ll just throw the entire thing out, then.” It just makes me think -- you threw out a perfectly good work for that?! That’s such a waste!
First of all, Toei and Bandai don’t work that way
In general, a lot of the contradictions in the series have a “right hand is not talking to left hand” problem, because as much as we would like to believe that a Digimon series is written by a single consistent entity, the franchise itself is a huge trade-off between Toei and Bandai, and a lot of things from Bandai -- spinoffs, crossover material, games, what have you -- don’t exactly have a stellar track record of being vetted by Toei anime staff. It’s pretty well-known that game portrayals of certain characters can be really off or have misleading info, and even V-Tamer’s somewhat guilty of it. So this is going to happen no matter whether you like it or not, and it happens with any long-running kids’ series that involves a collaboration between multiple companies like this.
Moreover, the traditional custom for Toei “side movies” (in this case, meaning things like the original movie, Our War Game!, Hurricane Touchdown, and Diablomon Strikes Back) is that they’re produced with minimal involvement from the original series’s core staff -- at most, the producer is lightly involved -- and are sometimes even worked on simultaneously with the start of the original series, so you often end up with a movie that’s impossible to fit anywhere in the series timeline because there wasn’t any communication with the two sides. And for that, it’s all too easy to dismiss those movies as “non-canon”, with the fanbase arbitrarily deciding that canon ones are canon because they fit -- but Toei itself has never taken this stance.
The other thing is that, given that Adventure/02 is famous for its ridiculous level of worldbuilding consistency thanks to its director Kakudou’s conscientious efforts on it, it means that as a result, anything not made by him was prone to running afoul on it, and it’s not like the stance back then was to just reject all of it wholesale. “Doesn’t comply with the lore” is so often equated with “not canon”, but Kakudou, the author of that lore, not only made no indication of invalidating or disliking those non-compliant things, but also conversely made an active effort to make those things relevant in spite of that! (See: Our War Game! below.) The official stance is to not deny those works for being noncompliant -- it’s just that Kakudou seems to be the detail-oriented kind of person who personally prefers to work with things that have a high level of consistency (he’s very quick to say “I wasn’t involved on that” whenever someone brings up something from said external materials, not in any condescending way, just “I wasn’t involved, so don’t attribute that to me”). In fact, one of the reasons there wasn’t initially a third Adventure series was that he had difficulty finding a way to adhere to the higher-ups’ pressure to keep all of these contradictions consistent -- so the official stance itself is to try and maintain all of those side works, and that it would be better to end the series itself than to have to do something like deny them.
Which makes things very frustrating for the fans, of course, but nevertheless, that’s how it is -- even back in 2000, the right-hand-not-talking-to-left-hand phenomenon was this significant! And it would have been easy for official to step in and go “okay, we’ll put a statement out here that these don’t apply,” but no, the stance was be that it would be better to stop dragging it out longer and cancel a whole series than to deny those works, which leads us to the current situation. (Plus, think how insulting it would feel from a PR perspective if someone got attached to one of those “non-canon” materials only for official to come out and outright say “yeah this doesn’t count anymore”; we can name examples of this happening in other franchises that have understandably gotten a lot of people upset, and it would be especially offensive to do this right after said material had been released.)
Bolstering the concept of official staff’s very loose opinion of “canon” are the Adventure novels, which were supervised by Kakudou himself and written by Digimon episode screenwriter Masaki Hiro, and are non-compliant with Adventure timeline by design, because it’d be bad for the format to try and depict every single detail in the anime in the form of three novels. Several events are condensed or shuffled out of order, or even sometimes completely different (Koushirou’s incident with Vadermon goes very differently from the anime version). Despite that, this is said directly to be intended as a series of novels to help people understand Adventure and 02 better, and several details in Two-and-a-Half Year Break and Spring 2003 are incredibly consistent with it (namely in the sense of details meant to retroactively connect Adventure to 02, and other background details like Daisuke’s backstory). So you are supposed to do some kind of mental leap where you don’t take the contradictions around the actual events too seriously, but still accept the spirit and the background information you learn from it and retroactively apply it to Adventure and 02 -- and, presumably, that’s probably what you’re expected to do with everything else, too.
And this isn’t even getting into the fact that the anime itself has occasional contradictions and errors due to things like animator error or simply different writers writing different episodes -- the Adventure and 02 staff were certainly very detail-oriented, but they are human and of course inevitably slipped up here and there. How seriously do you take honorifics shifting from episode to episode in ways that don’t seem intentional, or the fact every background material refers to Osamu and Ken having a bunk bed and yet the actual episode with both of them fails to depict it? How do you deal with the fact that the Animation Chronicle is one of the most extensively useful post-02 reference materials with tons of production background info not revealed in the anime, and yet is infamously full of suspected typos that would cause some pretty massive implications if true, or all of those other Bandai and Shueisha-commissioned “side books” and other pieces of media meant to entertain the kids while the series was airing but clearly had no input from Toei staff whatsoever?
In the end, frustrating as it is, the answer seems to be the same as ever: figure it out yourself.
The standards for what’s “canon” and “not canon” are way too arbitrary
Let’s look at a handful of things that have been historically dismissed as “non-canon” by the fanbase:
The Adventure mini dramas and Armor Evolution to the Unknown: Drama CDs that were generally dismissed as non-canon because they’re “too crack” to be canon (their writing style is of the “it’s okay to push the boundaries of characterization for the sake of comedy” sort, and it wouldn’t be until later when we finally got some more serious drama CDs). The latter is full of honorific inconsistencies, most prominently Daisuke and Ken still being on surname basis at a time they’re not supposed to be (due to the fact that it was released while the series was still being produced). But official word is that you’re still supposed to consider them canon -- and yes, that’s Kakudou himself giving official sanction to a drama CD that involved a massive amount of fourth wall breaking and a completely unexplained reunion between the Adventure kids and their Digimon sometime between 1999 and 2002 (apparently this wasn’t the only one, either). How is this supposed to work? Figure it out yourself.
Hurricane Touchdown: The funny part is that up until Kizuna validated Wallace’s existence, there was no actual consistent agreement on why this movie shouldn’t be canon (the Western side being “evolutionary form timeline violations”, the Japanese side being Wallace’s status as a Chosen Child prior to 1995), which really goes to show you how arbitrary all of this is. It also has a sequel drama CD in the form of The Door to Summer, which is also contradictory with Hurricane Touchdown’s ending, so we’ve got two layers of “it can’t be canon because...” -- and yet it has a lot of interesting Daisuke characterization, and, heck, the whole character of Wallace himself, that would all be rejected if you throw this out wholesale. Then Kizuna came along, and there’s a general sense of hesitation against easily denying officially-sanctioned “main” entries like that, which retroactively forced people to somehow skip past all that and accept it, just for the sake of Kizuna’s notability.
Diablomon Strikes Back: Similar to the above, it used to be constantly dismissed as “a non-canon fun movie” because of the evolutionary forms that appear in it, despite the fact that 02 itself established that it wasn’t that hard to restore evolutionary forms if you figured something out. Somehow, a ton of people treated it as such an impossibility that “they figured it out in the first three months of 2003″ would be a viable explanation, and yet official word is that of the second through fourth movies, this is the one that had the most amount of initial consultation with the TV anime staff! And then tri. and Kizuna came along and clearly had high-level evolutions in play too, and dismissing DSB on these grounds meant dismissing those by proxy, and a lot of people were too intimidated to do that and decided to retroactively validate DSB instead, after years of having dismissed it for this reason. Again: look how arbitrary this all is.
The tri. stage play: Mainly because its timeline of events doesn’t fit tri. at all (in regards to the reboot and part 5). This is a fair assessment to make in light of the fact that it doesn’t seem to work very hard to be compliant with the very series it’s branded with, but, funnily enough, it’s actually more lore-compliant with the original Adventure and 02 than the tri. anime series is, and yet the few minor contradictions it makes with the tri. anime series are sufficient to consider it completely kicked out of canon, yet those same people who declare it so aren’t as willing to hold the anime to that same standard just because it holds a more prominent “main” position.
On the other hand, let’s look at some of the things that have been more likely to be accepted than the above:
Our War Game!: Reading this is probably going to make everyone go “whaaaaaat?”, but yep: according to Kakudou, the second through fourth movies were all made without his supervision or involvement and thus have lore contradictions (although he also made sure to say that they’re very fine movies, too). We still haven’t figured out what the lore contradiction is, and so the fanbase considers it canon, and even 02 itself makes multiple references to “the Diablomon incident” in 2000, so you can’t consider this non-canon in the slightest...but yes, according to the official side, it’s actually got a contradictory incursion somewhere in there. There is one hypothesis as to what it is, and it’s such a minor thing that no fan or even official member of staff would dare deny the movie for it, but it still contributes to how arbitrary this entire concept is: Kakudou didn’t want to give anyone (except Miyako, who’s based off a real person) canonical birthdays or blood types for the sake of preventing horoscoping, but Sora’s birthday is portrayed as being around March in the movie. And yes, Kakudou himself refers to this as being something that only happened because he wasn’t involved. (Remember what I said about him historically being quick to disclaim involvement on anything he wasn’t involved on, regardless of how much of a minor detail it is, yet doesn’t necessarily intend to deny the work entirely due to it?)
Tag Tamers: A very vital part of Ken’s backstory that establishes a lot of context behind the Dark Seed and the elusive Akiyama Ryou, which also does not make sense with 02′s timeline and characterization at all, presumably because Bandai and Toei weren’t properly communicating on what kind of details they needed to iron out for this. But of course, all of us would like some explanation to Ken’s backstory, and we have to apply some kind of logic as to how that makes sense, and I’ve yet to see people declare Tag Tamers (or any of the other WonderSwan games) as entirely non-canon as a result.
tri.: For obvious reasons, it’s a “major entry in the franchise”, so people are generally more averse to dismissing it so easily (or, at least, for reasons that aren’t related to pure preference), but I find it rather ironic that Kizuna’s the one that got all the attention for apparently being lore non-compliant, when the exact same lore points mentioned in Kakudou’s reasoning as to why it’s non-compliant (along with a ton of things that actually were in Adventure and 02′s text) are gone against even more regularly and prominently in tri., whereas Kizuna still goes out of its way to adhere to most of these and only seems to have incurred a contradiction in terms of originally intended ideology, and, possibly, its extensive use of the aforementioned movies. (Recall that this got brought up for Kizuna specifically because Kakudou was initially consulted for it; he wasn’t involved in tri. to begin with at all.) See above on how people’s unwillingness to write this one off so easily despite everything ended up retroactively dragging DSB into “accepted canon” territory; that’s how arbitrary this entire thing is.
Then, tied to all of this and making it even more confusing is Kizuna, which, again, putting all issues of personal preference aside, is basically being torn back and forth between all of these whenever you try to apply one of the above arbitrary standards. It’s allegedly lore-noncompliant with Kakudou’s lore and thus lacks his involvement, but it does have the involvement of original series producer Seki Hiromi who was known to be responsible for the series’s original human drama themes (including the premise of 02 itself) and personally vetted the scripts so that everyone could be properly in-character and the original themes still intact; it’s supposedly a “main” entry to the point where people will stop denying older works’ canonicity because of it (see Hurricane Touchdown above), but, legally speaking, is actually classified in the same “gekijouban” category that the first four movies and things like the Tamers through Savers movies are; the staff will say to hell and back that the 02 epilogue still holds (and the movie makes abundant retroactive references in both worldbuilding and themes to it), but many people out there will still insist that the movie ending that way means that (like with DSB above) “they figured it out” between the movie’s ending and the epilogue is apparently some kind of impossibility, and either the movie is non-canon or the 02 epilogue is invalidated now. (My personal stance on this is that the epilogue itself provides the answer to how they figure it out if you look closely at the movie’s themes, but that’s a tangent.)
The point I’m trying to make is that regardless of whatever stance you take on all of the above points, this is all extremely arbitrary, and these fanbase rationalizations on why this and that isn’t canon are constantly contradicting each other, shifting, and occasionally based on really meaningless things. And, again, it’s fine if you’re saying that you don’t consider this or that canon because you personally dislike it or where it went, or you find it difficult to work with, or between two contradictory things you prefer one or the other (I certainly have my fair share of strong opinions in this regard) -- but it would be better if we all admitted this and went “I just don’t consider this canon” instead of acting like there were ever some universal consensus or official backing.
"It didn’t happen this exact way, but something resembling it still happened”
So, we’re in this uncomfortable situation where we’ve been handed a ball of knots and have to work with it (a very frustrating situation especially for fanfic writers), and I have to personally say that I think all of this comes from people having far too inflexible of a concept of “canon” and “not canon”, especially to the point of rejecting a full-on perfectly fine entry just because of one timeline issue. I honestly think it’d be better if we could rather take a certain stance close to the Pixiv dictionary wiki’s view of how Wallace can appear in Kizuna: “(some version of) Wallace exists in the timeline of the main story.”
Right, so: Hurricane Touchdown is contradictory. The evolutions don’t work at that point in timeline, and Wallace shouldn’t be able to be a Chosen Child from before 1995. Those things don’t work with Adventure and 02′s timeline and lore. However, let’s look at the following story: let’s say that, between 02 episodes 14 and 15 (when the movie first screened), while school was on break, Daisuke and his friends went on a summer adventure to the US and met a boy named Wallace, who had a struggle regarding one of his partners losing his sanity, and bonded with him and helped put his partner to rest. No part of this contradicts 02 at all. There we go! So we can safely say that some story that mostly resembled Hurricane Touchdown happened in the canon timeline. Some of its details weren’t exactly the way they happened in “the movie we, as the audience, saw” -- but something that substantially resembled the movie still happened in the universe of Daisuke and his friends. And you can apply that same logic to Tag Tamers, or any other vital canonical but ostensibly contradictory material -- the media that we as the audience got may not accurately reflect the events in universe, but there’s absolutely nothing saying that some more timeline and lore-consistent alternate version didn’t happen in canon instead.
Moreover, even Adventure/02 itself gives you a bit of precedent for this concept -- namely, the fact that the final episode of 02 reveals that the entirety of Adventure and 02 is part of Takeru’s novels. It’s a pretty common theory that there might be differences in the way “the story we got” was presented, versus how they actually happened in the world Takeru lived in -- of course, Takeru certainly went out of his way to remove as much bias from the situation as he could, but you can hardly say that he, as a human, would be completely free from it, and he himself even admits that everyone he consulted had differing opinions on the events in question. And not every single piece of Digimon media has the Hirata-Hiroaki-as-Takeru narrator, which means that perhaps it’s not entirely out of the question that the different takes on the stories that the Tokyo Chosen Children went through in their youth would not be entirely consistent with each other, depending on who’s telling it. But that doesn’t mean that those events necessarily didn’t happen at all, just that some of the details were different from what we as the audience saw.
In the end, I leave the rest to everyone else to figure out -- as I said, I think this is a decision everyone will have to make for themselves, whether they’re a fanfic writer picking and choosing what to include for the sake of a coherent fic, or whether they’re just expressing a preference to not have to think too hard about or work with something they’re turned off by. (And in the case that there is someone who expresses their dislike of working with something and doesn’t want to consider it canon, I think it’s very rude to give them grief for that, and conversely, if you don’t want to consider something canon but encounter someone who doesn’t have as much of a problem with it, it’s very rude to try and expect them to change their opinion to yours.) But I do think it would do well for all of us to have a bit more of an open mind and a creative attitude towards these kinds of things before trying to shove everything into a “fully canon” and “fully not canon” binary.
